or Ave (livoriiiii.;; spiiu-s, whicli give it a palinato appearance; the clasp proper is from 

 two to three times as long as broad, has a rather broadly rounded, spinigerous hinder 

 border, and a considerable laminate dentation near the tip within, and also near the 

 middle of the lower border Avithin; the upper process is small, of equal breadth, 

 broadly rounded at the tip, a])out twice as long as broad, a little incurved but mainly 

 parallel with the clasp.

Malformation. In a female specimen I find on the lower wing of both sides, a 

 curious though unequal development of the upper subcostal nervule; on the right 

 side, at about two-rtfths the distance from its origin, the vein forks, and then again 

 unites, forming a slight loop less than 1.5 mm. long; on the left wing, at a little 

 before the middle, it forks in a similar manner, and in such a way that one branch 

 seems no more important than the other, that is, -without denuding, one cannot tell 

 Avhether it sends ofl' a superior or inferior branch; the upper branch, after diverging 

 scarcely more than .5 mm. from the lower, continues parallel to it a short distance 

 and then disappears ; its total length is 2 mm ; the lower, after being by this deflected 

 a little from the course of the nervule, returns to it again as soon as the upper has 

 disappeared. 



Egg (64: 23) equally high and broad, narrowing with considerable regularity to the 

 summit, w'hich is about half as broad as the base; vertical ridges very numerous, per- 

 haps about forty, at extreme base, wliere they are scarcely more than .05 mm. apart, 

 many either amalgamating, generally a little below the middle, or terminating inde- 

 pendently, generally a little above the middle, so that at summit there are only eight 

 or nine ridges, and in the upper portion of the egg the interspaces have a width of 

 about .1 mm.; the cross lines are from .04-. 06 mm. apart, and the surface is uni- 

 formly and minutely punctate and glistening ; the summit depression is saucer-shaped, 

 rather shallow^ about .15 mm. in width, and the micropyle rosette (67:8) is about 

 .09 in diameter, consisting of a central circular cell, .01 mm. in diameter, and around 

 it two irregular ranges of about twenty-five pentagonal cells, the inner ones longer 

 than broad, the others about equal, the whole rosette abruptly terminating against the 

 surface beyond, the entire depression very minutely punctulate. 



Caterpillar. First stage. Head dusky; body pale greenish brown, mottled with 

 dull Avhite, encircling the black base of the hairs; hairs black. Length, 4.5 mm.; 

 breadth, .64 mm. 



Second stage. Head blackish. Body dull feiTuginous, dusky at the incisures, a .stig- 

 matal series of roundish, dull white spots at either extremity of each segment, those of 

 adjoining segments separated only by the incisures; a similar dorsal series; spines 

 and papillae on which they rest, black; legs and prolegs black; spines of equal length 

 throughout. Length, 7.9 mm; breadth, 1 mm. ; length anterior spines, .25 mm. 



Tliird stage. Head black. Body orange ferruginous, with an interrupted, dorsal, dull 

 whitish stripe and a suprastigmatal, moderately narrow, white belt, broken narrowly 

 once or twice at the anterior extremity of each segment, and tapering just beyond the 

 middle of each segment until lost near the middle of the posterior half ; extreme base 

 of legs and prolegs white, beyond black; spines black, the anterior subdorsal pair 

 larger by one-third than the others of the same row. Length 11.8 mm. ; breadth, 

 1.4 mm. ; length anterior spines, 1.25 mm. 



Fiiurth stage. Head black. Body dark orange ferruginous ; a dorsal and suprastig- 

 matal, narrow white stripe broken bj' several transverse black lines on each segment.
